Warning

Disabling antivirus or antispyware software might increase your security risk. We recommend that you turn this software back on as soon as possible. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.

To turn off your antivirus or antispyware programs

Close all programs, and then restart your computer.

After restarting, turn off all antivirus and antispyware programs that might run during the startup process.

You can usually turn off the program from the notification area, at the far right of the taskbar. To turn off a program from the notification area, right-click the program icon, and then click Close, Disable, Exit, or a similar option. If these options aren't available, you might have to open the program, and then turn it off using options from within the program.

As soon as you close the antivirus or the antispyware program, try to install the service pack again.

After you've installed the service pack, turn on all antivirus and antispyware programs.
